To understand whether soluble fiber (SF) with high water-binding capacity (WBC), swelling capacity (SC) and fermentability reduces food intake and whether it does so by promoting satiety or satiation or both, we investigated the effects of different SFs with these properties on the food intake in rats. Thirty-two male Sprague-Dawley rats were randomized to four equal groups and fed the control ...

In last few decades, indigestible carbohydrates as dietary fiber have attracted interest of food scientists and technologists due to its several physiological benefits. Dietary fibers are generally of two types based on their solubility, i.e. soluble and insoluble dietary fiber. Significant physicochemical properties of dietary fiber include solubility, viscosity, water holding capacity, bulkin...

Twelve strains of lactobacilli were tested for their growth and ability to utilise six prebiotics (pure substances and commercially available prebiotics) as a sole carbon source. All strains showed a considerable growth on all prebiotics tested. Inulin was the best carbohydrate source for lactobacilli, followed by lactulose and raffinose. A massive increase of viable cells on commercial prebiot...

Opinions vary regarding how much distiller’s grains (DG) can be used effectively in lactation rations. In order to better understand conflicting reports and recommendations about the effect of DG on milk yield we examined 23 studies about DG in the dairy science literature. Inclusion of DG in treatment diets ranged from 4 to 42% of dietary DM across all studies. Our analysis of the entire datab...

The fermentability of a corn cob, acid-hydrolysed hemicellulose by Pichia stipitis was considerably improved by pre-treatment with Ca(OH)2. The total sugars utilized and ethanol yield for the untreated hydrolysate were 18% and 0.21 g/g, respectively, compared with 82% and 0.32 g/g respectively for the treated material. Adaptation of the yeast to the hydrolysate resulted in a significantly highe...

Since potassium and magnesium ions have been shown to favor the formation of acetone from pyruvate by suspensions of Clostridium acetobutylicum (Weizmann) (1) and since these cations are known to catalyze the transformation of pyruvate into phosphoenolpyruvate (2), there was a possibility that the latter may be an intermediate in the butanol-acetone fermentation. No attempt has so far been made...

Lignocellulosic residues (wheat straw, corncobs, and cornstalks) were treated with a dilute alkaline solution of hydrogen peroxide and suspended in cattle rumen in situ to measure microbial degradation. The rate and extent of dry matter disappearance were markedly increased as a result of the treatment. Results in vivo indicate that this treatment increases the fermentability of wheat straw str...
